Detailed explanation of numpy version query method

Numpy is a Python scientific computing library that provides a wealth of array operation functions and tools. When upgrading the Numpy version, you need to query the current version to ensure compatibility. This article will introduce the method of Numpy version query in detail and provide specific code examples.

Method 1: Use Python code to query the Numpy version

You can easily query the Numpy version using Python code. The following is the implementation method and sample code:

import numpy as np print(np.__version__)

Run the above code, You can get the currently installed Numpy version. For example, if the current Numpy version is 1.19.2, the output is:

1.19.2

This method is simple and direct and suitable for Python developers. However, this method cannot be used if Numpy is not installed in the current environment. At this point, we can use pip to query the Numpy version.

Method 2: Use pip to query the Numpy version

Pip is a Python package management tool that can be used to query and update installed libraries. The following is the implementation method and code for querying the Numpy version through pip:

pip show numpy

Run the above code to get the currently installed Numpy version. For example, if the current Numpy version is 1.19.2, the output is:

Name: numpy Version: 1.19.2 Summary: NumPy is the fundamental package for array computing with Python.

This method is suitable for Python developers operating in the terminal or command line. However, if you use Anaconda or another scientific computing platform, you can query the Numpy version using the following method.

Method 3: Use Anaconda to query the Numpy version

If you use Anaconda or a similar platform, you can use the following method to query the Numpy version:

1. Open Anaconda Navigator
2. Click on the Environment option
3. Under the "Installed" tab, find and select the numpy library
4. View the numpy version at the bottom

For example, if the current Numpy version is 1.19.2, the output is:

Name: NumPy Version: 1.19.2

This method is suitable for developers using Anaconda or scientific computing platforms. The above three methods allow you to easily query the Numpy version and ensure the compatibility of your code.

Summary

This article introduces three ways to query the Numpy version: using Python code, using pip, and using Anaconda. The above methods are suitable for different Python developers and environments. You can choose one of the methods to query the Numpy version according to your needs. I hope this article is helpful to you, thank you for reading!
